Okay...Instead of using the brew lever to make it come back to life, tomorrow morning when it stops at too low a temp, just thump it a couple of times, doesn't have to be hard. If the vibration of your pump is enough to get the relay to make contact, a little thump should do the trick.

Tiny green circuit board with 4 wires connected to it, a small resistor and a plastic box with electrical contacts inside. It will either be riding on your Pressostat if your machine is many years old, or it will be inside the left wall of the machine, mounted to the frame.Now that it is dying, consider replacing it with a much better, solid-state relay once, rather than having to replace it with its own kin every year.

Mdiddy - if you decide to do this and have the time i'd really appreciate it if you took pics of the install... i'd like to replace the relay with a solid state on my machine but have no idea how to do it... to be honest i don't know what type of relay i'm even looking for. is this it: https://www.sparkfun.com/products/10636

Photo of relay location. It is the entire unit the arrow points to. You disconnect the three connections, pull the board and reconnect the new one. You only need to remove the one machine side panel (the one with the on/off switch).

Biggest problem with solid state relays is that they switch off of DC voltage, so you'd need a rectifier to convert AC in the machine into DC; my EE know-how isn't good enough to make a decent solution. That part in particular isn't rated high enough to run in an espresso machine, it should have a minimum current rating of 15A.

That: https://www.sparkfun.com/products/10636is not the right thing. Sorry.

You'd need to get a bigger relay to be sure it will be reliable. No sense in installing another that will need replacing every few years. You can get a decent Omron one that is designed to operate on the 120VAC that your machine is already providing through the pressostat...If I can find pictures of an install and a part number I will post further after the weekend.
